Remove center and Stb side hatches and it'll be on the Stb side of the engine. You have to remove the pump completely, no way to do it place.
Whether you remove the center hatch and slide the bigger one over is up to you. With both out, you can lay across the engine or put one leg in front of the engine and stand there. You just need to loosen the two bolts that are facing UP to get it out.
Remember to mark the direction of the impellor fins on the pump body so you get the new impellor going in the same direction.

If you find there is blades missing from the impeller you must find them, they ussually end up in the coolers.

When you install the impeller it helps to coat it with dish soap. Slides right in. Another tip is to take a cable tie and slowly cinch it onto the new impeller while rotating the fins of the impeller in the direction you want them to end up. Once you have the impeller half way into the housing cut the cable tie off and finish installing the impeller the rest of the way in.
